  • 2 Channel Preamp Input and Output Connect RCA's directly from your source unit to allow the full signal to pass through the PB-DBR1 for processing to the output RCA connection for your amplifier.
  • User Adjustable Center Frequency the Sweep adjustment allows you to set your center frequency. This is the middle of the frequency range you want to restore, once set you will need to adjust how wide of a range you want to be affected by the processor.
